javax.naming.directory.SchemaViolationException on LDAP

[Simpson Kumar]

I'm trying to update an attribute which contains different values, ex: objectclass, and it contains like top, person, inetOrgPerson, etc..
When I tried to updated, I got the following error

 
javax.naming.directory.SchemaViolationException: [LDAP: error code 65 - Object Class Violation]; remaining name 'uid=skk27test1,ou=people,dc=georgetown,dc=edu'
	at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3036)
	at com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2951)

	at javax.naming.directory.InitialDirContext.modifyAttributes(InitialDirContext.java:138)
	at edu.georgetown.netid.test.SimpleAuthentication.main(SimpleAuthentication.java:61)
 

and the code I'm using is

  DirContext authContext = new InitialDirContext(authEnv);

String dn = "uid=skk27test1,ou=people,dc=georgetown,dc=edu";
	    		//updating multiple attribute values for an attribute
Attributes container = new BasicAttributes(true);
Attribute objClasses = new BasicAttribute("objectclass");
objClasses.add("top");
objClasses.add("person");
objClasses.add("organizationalPerson");
objClasses.add("inetOrgPerson");	    		
container.put(objClasses);
authContext.modifyAttributes(dn,DirContext.REPLACE_ATTRIBUTE, container);
  

I can update a single attribute successfully, the following is the code

 //updating single attribute value for an attribute
ModificationItem[] mods = new ModificationItem[1];
mods[0] = new ModificationItem(DirContext.REPLACE_ATTRIBUTE,
	            		new BasicAttribute("gubuildingname", "Harris1"));
authContext.modifyAttributes(name+",dc=georgetown,dc=edu", mods);
   

I don't know why I'm failing to get update the objectclass attribute.

I got the solution..

Actually I missed one attribute which should be a mandatory. I compared the attributes in the LDAP request that fails to the schema.
I came to know there is most likely a must attribute missing, maybe from an inherited object class.

Attributes container = new BasicAttributes(true);  
 Attribute objClasses = new BasicAttribute("objectclass");  
 objClasses.add("top");  
 objClasses.add("person");  
 objClasses.add("organizationalPerson");  
 objClasses.add("inetOrgPerson");                  
 objClasses.add("guPerson");                  
 container.put(objClasses);  
 authContext.modifyAttributes(dn,DirContext.REPLACE_ATTRIBUTE, container);  

In the above code, earlier I missed to add " objClasses.add("guPerson");", the guPerson attribute value is mandatory.
Now I can modify the results.
